To all whom 'it mag/concern:

Be it known that I, ALONZO vDAVID MOORE, a citizen ofthe United States, residing at Needles, county ofSanBernardino, and State of California, have invented certain new and` useful Improvementsin Crude-Oil Burners, of which the following is a speciiication. j y My invention relates ,to .crude oil burners. In the use of crude oil burners in ,steam boiler furnaces a veryhigh degree of heatis necessary to cause theA vaporized oilto'turn into gas and obtain `what is knownV as a"l gas re, andra defect common to burners now in use is that much ofthe oil fails to `va'porize and become converted into gas yand passes off in the shape of smokeicausing considerable wastageof, oil. Crude oilburners are commonly employed in steam boiler furnaces and are used in a deeppanand much ofthe oil is consumed beneath V,the heatingsurface of the iire-boznthe` pan being .usually'disposed quite a distance belowrltheuheating.

surface in order` to causethevaporized oilto become converted-into a gaseous condltion and produce thedesiredfgasiire which is necessary to obtain good results. Burners of this character areusually placed beneath the mud rin `at the'rear end of the lire-box, with the bri ge wall `and arch straight ahead and the use of the deep pan commonly em- 'ployedfis to allow the oiljto strike the bridge wall under the arch and provide room for the ilames to pass back andu into the heating surface, thus obtaining su cient heat to gen- The foregoing disposition of crude oil burners in steam boiler furnaces is necessary where a burner is what is known as a straight shot burner,asa brdgewall must be employedfor the heat is'too severeV 40 on the boiler sheet if made to strike direct thereon. A Y Y p l The object of this invention is to provide a crude oil burner for use in steam boiler furnaces which will be of such improved construction that theoil'w'ill be sprayed in anV im roved fashion in `just the shape ofthe arc but without touching the brick thereof so that when the brick have attaineda white heat, the sprayed-'oil is immediately convverted into aclear gas iirein front of the i `burner and all of the oil consumed in usefull heat and not wastedin unconsumed products of combustion as has Vbeen the caseheretol. fore.

with a flat panflush with the bottom of the dire-box, thus doing away vwith all of the brick previously used in the deep pan and saving the cost of this brick-work, as the bridge wall, where most of the brickare used A` stillffurther object of the` invention is the provision cfa crude oil burner having a nozzle ofimproved construction to s ray the oil .in more or less fan shape and, furt 1er, to provide a novel form of nozzle which may be ad- `justed'rto modify `the spraying flow of the l'crude oil.

vThe invention is set forth in detail and the novel features are recited in the 'appended claims. l

ln the accompanyingdrawings-Figure 1 isa side elevation of. theVV burner; Fig. 2, a`

plan view;l Fig, a longitudinal section on line 3 3 of Fig. 2; Fig. 4, a horizontal section on lined-#l of Fig. l; Fi 5, a sectional detail -of the adjustable nozz e; and Figs. 6 land `7, details of a modified form of nozzle.

The compressed air or steam is conducted into the commingling chamber '1 in the tubularnozzle 2 through a duct 3, while the oil flows into the commingling chamber` through a ductfl, from suitable sources of supply. The tubular nozzle 2 is cut away obliquely to its horizontal diameter at 5, leaving the lower portion 6 of the nozzle of semicircular shape and `provided with the Vshoulders 7.

' VThe spraying plug `8 has its bottom portion 9 rounded to snugly lit the lower part of nozzle 2 and prevent the escape of any olor air or steam between said rounded bottom ortion 9 and the bottom portion of the nozz e. The upper face 10 of the spraying plug is sharply beveled or cut away in the direction of its length until it substantially; merges, at 11, into the bottom of the inner portion of the tubular nozzle 2, said cut away portion 10 being convex upwardly to some extent. The discharge portion 12 of thespraying plug `extends from the point 13 outwardly at somewhat less of an angle than the bevel of part 10 and is rounded in cross-section to more nearly semi-circular configuration, they purpose of `which is to spread or distribute the oil and air or steam substantially parallel to the under-cut or beveled obliquely cut-away portion 5 of nozzle 2, while the lip or flange terminates in shoulders 15 which rest upon the shoulders 7.

In the bottom of nozzle 2 is an elongated slot 16, through Which passes a screw 17 having a nut and washer 18 threaded into the spraying plug at 19, thus providing means for adjusting the spraying plug in and out of the nozzle 2 to the desired extent to regulate the size of the discharge opening and control the spraying action.

In .the modiiication shown in Figs. 6 and 7, the spraying plug is of the same shape as heretofore described, but is formed or cast integral with the bottom part of the nozzle 2 as shown at 20, While the outer portion 21 of the plug is made in a separate piece and adjustably connected to the plug by screws 22. This construction is practically as eflicient and satisfactory as that previously described, but is much cheaper to produce. The oil and compressed air, or steam striking the spraying plug, are commingled and spread in the form of a sheet corresponding to the shape of the plug and issue from the discharge mouth in a fan-shaped or substantially semi-circular sheet which is thrown at an inclination upwardly and may be regulated and controlled by adjustment to bring about the desired effect.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a burner of the class described, the combination with a nozzle provided with a commingling chamber having at one side of the nozzle an exit mouth of arc-shape, of a transversely curved inclined surface within the nozzle and extending in general transverse relation to the nozzle and leading from one side of the interior thereof to the exit mouth at the opposite side thereof, and means for introducing the oil and vaporizing element into the commingling chamber prior to their impinging the inclined surface.

2. In a burner of the class described, the combination with a nozzle provided with a commingling chamber having at one side of the nozzle an exit mouth of arc-shape, of a transversely curved inclined surface within the nozzle and extending in general transverse relation to the nozzle and leading from one side of the interior thereof to a point adjacent the arc-shaped exit mouth, and a spraying fiange or lip of arc shape located adjacent the exit mouth.

3. In a burner of the class described, the combination with a nozzle provided with a commingling chamber having an exit mouth of arc shape, of a spraying flange or lip of arc shape disposed beyond and substantially parallel to the said mouth, and copcrating shoulders or supports on the nozzle and spraying lip or flange, together with means for adjusting the lip or flange toward or away from the nozzle to vary the size of the mouth.

In testimony whereof, I hereunto allix my signature in presence of two witnesses.
